Hey group I know this has been asked a thousand times. . So much so that I am confused. but here goes I wanted to use a Samsung galaxy tab s 2. or possible a tab 4 with a sunshade. with my eyesight I just need a bigger screen and sun shade. I have a lot of questions before I buy one like Do I just need wI fI not cell service? does the DJI go app work the same on a Samsung tab?
